Just to let you guys know that ISA Server 2004 SP2 is to be available in the end of Jan 2006.
Usual bug fixes as well as the extra features below:
- Support for compressed HTTP content
- BITS caching
- The HTTP QoS feature
Out of all the above the "support for compressed HTTP content" is perhaps the most important one as it will speed up web access and also speed up OWA.
